Low power modes in STM32WB mode and how to wake up the mcu

PMana.1 · ‎2022-03-21

Hello,

I am working on an application and the power consumption is a bit high as of now. I would like to know the different low power modes and how to wake up from those modes. Could you please help me with the documentation and sample codes?

The reference manual discusses each low power mode in detail including what is required to enter and exit from them.

Hi @PMana.1 ,

Besides to the reference manual as suggested by @TDK , I suggest:

AN5071: STM32WB Series microcontrollers ultra-low-power features overview
STM32CubeWB examples like the ones available under Nucleo_WB_PWR or Nucleo_WB_PWR_LL.
